Hah, if I knew the answer to that one, I'd be rich and living in Cabo San Pluto!

i think of you will discover that warmth in itself isn't some thing which would be measured. in basic terms that is result on some thing else. with the aid of fact the solar is often greater or less the comparable temperature there is not any way you could ever be waiting to tell how long it took for the waste made from warmth, brought about by the reaction contained in the middle, to realize the exterior layer. it quite is purely an no longer possible calculation.

None of the above.

Many thousands of years.

(not millions)

Core - The Sun's Power Plant

Hydrogen inside the core is packed so tightly, and the temperature is so hot, that individual atoms ram into each other, forming heavier helium atoms and releasing energy in the process. This energy takes many thousands of years to make its way to the photosphere and out into space

To Michael (below)- Actually, heat does travel or move. The molecules of a hot object are in rapid motion; the hotter, the higher the average speed. If the object is gaseous the motion consists of free-path travel and collisions with other molecules. If it is liquid the paths between collisions are shorter, and if solid the motion is vibrational with no secular movement.

In conduction, heat is transferred by collisions between molecule populations with different average speeds. The transfer continues until both populations have the same average speed.

In convection, heat is transferred by mixing fluids of differing temperature. The mixing can be forced or driven by density differences caused by temperature difference. It is not necessary that molecular collisions occur in convection, since mixing alone changes the average molecular speeds.

In radiation, the molecular motion is converted to microwave or infrared energy by rigid motion of molecules or flexing of molecular bonds (ref.). Shorter wavelengths (light, UV, X-rays, gamma rays) are produced at higher temperatures where atomic electrons and nuclei may become involved. Radiative energy is not considered heat, but is converted to heat by absorption.

The number I've heard is 6 million years.
